WANG Junyan, HUANG Dexian. Process optimization of catalytic reforming based on differential evolution and HYSYS mechanism model[J]. CIESC Journal, 2008, (7): 1755-1760.DOI:
A kinetics model involving 18 lumped components and 31 reactions was selected and a mechanism model was built based on HYSYS simulation software. To establish the process optimization model
the objective was to maximize the yield of aromatics and the decision variables were inlet temperatures of four reactors. The optimization problem was solved by differential evolution and the constraints were handled by feasibility-based rule. The simulation results demonstrated the increase of aromatics yield and confirmed the effectiveness of differential evolution.
